My first objective in this paper is to synthesize, synoptically, the literature on oppression and liberation with the contributions to this special issue. To fulfil this aim I introduce a framework for understanding, resisting, and overcoming oppression. The framework consists of psychopolitical well-being; experiences, consequences, and sources of oppression; and actions toward liberation. Each of these components is subdivided into 3 domains of oppression and well-being: collective, relational, and personal. Experiences of suffering as well as resistance and agency are part of the framework. My second objective is to offer ways of closing the gap between research and action on oppression and liberation. To do so I suggest 2 types of psychopolitical validity: epistemic and transformative.  相似文献

Compliance with demanding requests that are normally ineffective may be increased by presenting a series of easy or high-probability (high-p) requests before the more demanding requests. Mace and his colleagues have discussed the effectiveness of the high-p procedure in relation to behavioral momentum—the tendency for behavior, once initiated and reinforced, to persist in the face of a challenge. The high-p procedure differs in several ways from that employed in laboratory research on momentum, and the methods and findings of basic research may not be relevant to applied work on compliance. This article reviews some laboratory procedures used in research on behavioral momentum, summarizes the major findings of that research, and discusses its relevance to the high-p procedure and its outcomes. Increased compliance with demanding requests following the high-p procedure can be understood in relation to the procedures and findings of basic research, but some questions arise in the process of translating research into application via the metaphor of momentum. These questions suggest some new directions for both experimental and applied behavior analysis.  相似文献

Basic findings indicate that the amount or magnitude of reinforcement can influence free-operant responding prior to and during extinction. In this study, the relation between reinforcement magnitude and adaptive behavior was evaluated with 3 children as part of treatment with differential reinforcement. In the first experiment, a communicative response was shaped and maintained by the same reinforcer that was found to maintain problem behavior. Two reinforcement magnitudes (20-s or 60-s access to toys or escape from demands) were compared and found to be associated with similar levels of resistance to extinction. The relation between reinforcement magnitude and response maintenance was further evaluated in the second experiment by exposing the communicative response to 20-s or 300-s access to toys or escape. Results for 2 participants suggested that this factor may alter the duration of postreinforcement pauses.  相似文献

A paradigm clash is occurring within behavior analysis. In the older paradigm, the molecular view, behavior consists of momentary or discrete responses that constitute instances of classes. Variation in response rate reflects variation in the strength or probability of the response class. The newer paradigm, the molar view, sees behavior as composed of activities that take up varying amounts of time. Whereas the molecular view takes response rate and choice to be \"derived\" measures and hence abstractions, the molar view takes response rate and choice to be concrete temporally extended behavioral allocations and regards momentary \"responses\" as abstractions. Research findings that point to variation in tempo, asymmetry in concurrent performance, and paradoxical resistance to change are readily interpretable when seen in the light of reinforcement and stimulus control of extended behavioral allocations or activities. Seen in the light of the ontological distinction between classes and individuals, extended behavioral allocations, like species in evolutionary taxonomy, constitute individuals, entities that change without changing their identity. Seeing allocations as individuals implies that less extended activities constitute parts of larger wholes rather than instances of classes. Both laboratory research and everyday behavior are explained plausibly in the light of concrete extended activities and their nesting. The molecular- view, because it requires discrete responses and contiguous events, relies on hypothetical stimuli and consequences to account for the same phenomena. One may prefer the molar view on grounds of elegance, integrative power, and plausibility.  相似文献

Nevin (1979) noted that preference in concurrent chains and resistance to change in multiple schedules were correlated, in that both measures were affected similarly by variations in parameters of reinforcement such as rate, immediacy, and magnitude. To investigate the relationship between preference and resistance to change directly, we used a within-session procedure that arranged concurrent chains in one half of the session and a multiple schedule in the other half. The same variable-interval schedules served as terminal links in concurrent chains and as the components of the multiple schedule, and were signaled by the same stimuli. After performances had stabilized, responding in the multiple schedule was disrupted by delivering response-independent reinforcement during the blackout periods between components. Both preference in concurrent chains and relative resistance to change of multiple-schedule responding were well described as power functions of relative reinforcement rate, as predicted by current quantitative models (Grace, 1994; Nevin, 1992b). In addition, unsystematic variation in preference and resistance to change was positively correlated, which suggests that preference and resistance to change are independent measures of a single construct. That construct could be described as the learning that occurs regarding the prevailing conditions of reinforcement in a distinctive stimulus situation.  相似文献

If, during training, one stimulus is correlated with a higher rate of reinforcement than another, responding will be more resistant to extinction in the presence of that higher rate signal, even if many of the reinforcers have been presented independently of responding. For the present study we asked if the response-independent reinforcers must be the same as the response-dependent reinforcers to enhance the response's persistence. Twelve Long-Evans hooded rats obtained 45-mg food pellets by lever pressing (variable-interval 100-s schedules) in the presence of two discriminative stimuli (blinking vs. steady lights) that alternated every minute during daily sessions. Also, in the presence of one of the stimuli (counterbalanced across rats), the rats received additional response-independent deliveries of sweetened condensed milk (a variable-time schedule). Extinction sessions were exactly like training sessions except that neither pellets nor milk were presented. Lever pressing was more resistant to extinction in the presence of the milk-correlated stimulus when (a) the size of the milk deliveries during training (under a variable-time 30 s schedule) was 0.04 ml (vs. 0.01 ml) and (b) 120-s or 240-s blackouts separated components. Response-independent reinforcers do not have to be the same as the response-dependent reinforcers to enhance persistence.  相似文献

Two experiments explored preference and resistance to change in concurrent chains in which the terminal links were variable-interval schedules that ended either after a single reinforcer had been delivered (variable duration) or after a fixed period of access to the schedule (constant duration). In Experiment 1, pigeons' preference between the same pair of terminal links overmatched relative reinforcement rate when the terminal links were of constant duration, but not when they were of variable duration. Responding during the richer terminal link decreased less, relative to baseline, when response-independent food was presented during the initial links according to a variable-time schedule. In Experiment 2, all subjects consistently preferred a terminal link that consisted of 20-s access to a variable-interval 20-s schedule over a terminal link that ended after one reinforcer had been delivered by the same schedule. Results of resistance-to-change tests corresponded to preference, as responding during the constant-duration terminal link decreased less, relative to baseline, when disrupted by both response-independent food during the initial links and prefeeding. Overall, these data extend the general covariation of preference and resistance to change seen in previous studies. However, they suggest that reinforcement numerosity, including variability in the number of reinforcers per terminal-link entry, may sometimes affect preference and resistance to change in ways that are difficult to explain in terms of current models.  相似文献

In 1994, out of a population of 45 million people an estimated 7.7 million people lived in informal settlements in South Africa (South African Institute of Race Relations, 1994). This article focuses on one community whose residents' desperation to own housing contributed to community disintegration, typified by infighting among women, and threats to human life. Issues of diversity became more prominent and destabilized community-building efforts. One effort to collaboratively break down barriers that deterred women from working together is presented to illustrate how these women created bonds based on \"discovered similarities.\" The participatory and personal-experience approach described here contributed to their becoming active protagonists of their learning and encouraged tolerance and understanding among community women from differing ethnic, linguistic, and political backgrounds. The article concludes with a discussion of the critical importance of recognizing and working with and through differences within the current South African reality.  相似文献

According to theoretical accounts of behavioral momentum, the Pavlovian stimulus—reinforcer contingency determines resistance to change. To assess this prediction, 8 pigeons were exposed to an unsignaled delay-of-reinforcement schedule (a tandem variable-interval fixed-time schedule), a signaled delay-of-reinforcement schedule (a chain variable-interval fixed-time schedule), and an immediate, zero-delay schedule of reinforcement in a three-component multiple schedule. The unsignaled delay and signaled delay schedules employed equal fixed-time delays, with the only difference being a stimulus change in the signaled delay schedule. Overall rates of reinforcement were equated for the three schedules. The Pavlovian contingency was identical for the unsignaled and immediate schedules, and response—reinforcer contiguity was degraded for the unsignaled schedule. Results from two disruption procedures (prefeeding subjects prior to experimental sessions and adding a variable-time schedule to timeout periods separating baseline components) demonstrated that response—reinforcer contiguity does play a role in determining resistance to change. The results from the extinction manipulation were not as clear. Responding in the unsignaled delay component was consistently less resistant to change than was responding in both the immediate and presignaled segments of the signaled delay components, contrary to the view that Pavlovian contingencies determine resistance to change. Probe tests further supported the resistance-to-change results, indicating consistency between resistance to change and preference, both of which are putative measures of response strength.  相似文献

The author challenges the traditional and still prevalent view of 'free association', arguing that it entails three forms of denial (also formulated in terms of corresponding myths): 1) denial of the patient's free agency; 2) denial of the patient's and the analyst's interpersonal infl uence; and 3) denial of the patient's share of responsibility for co-constructing the analytic relationship. That responsibility includes some degree of consideration of the analyst's needs. Sometimes, the patient's good judgment to that end may be refl ected in what is automatically and mistakenly reduced to a form of 'resistance'. Attention to the patient's responsibility must be balanced against the effort to provide a uniquely safe environment for the patient's revealing of shame and anxiety-ridden feelings and attitudes. But the therapeutic action of psychoanalysis, ideally, includes the cultivation, through lived experience, of the dialectical interplay of self-expression, on the one hand, and caring relational engagement, on the other. Recognition of the patient's free agency does not preclude exploration of constraining structures laid down in the past. On the contrary, it deepens such exploration. At the same time, it opens the door to the possibility of explicit recognition, via challenge, criticism, or affi rmation, of the patient's contributions to the analytic work.  相似文献
